My Perry Labs test can be interpretted to call for 2 tablespoons of SOLUBOR per 300 sq ft bed. I have 49 tomato plants staked in each 300 ft bed. It seems that diluting the boron source in water and spraying it is the most practical way to get even application. It seems spraying it directly on the tomatoes is probably the way to go HOWEVER, it's hard to imagine whath the conversion from boron-per-acre/sq ft would be if applied to the 50 plants. Could it be the same, since the plants would be sourcing boron from the 300 sq ft bed normally?
